Has anyone gotten the invaluable sweetfx configurator to work on windows 10 specifically for the game Arma 3?

SweetFX configurator? Do you mean the Framework Mediator? I'm pretty sure the SweetFX Configurator hasn't been continued for a very long time.

I used to run Sweetfx Configurator in windows 8 for the game Arma 3. http://sweetfx.thelazy.net/ Now that I've updated, it no longer works.

Yeah dude that hasn't been continued for quite some time now. It's not surprising to me that it doesn't work (In Windows 10? You said you updated, maybe Windows 8.1?) You can always use Reshade solutions. Reshade has a Framework, SweetFX 2.0 package, and a MasterEffect Package (and custom!) all under one roof. www.Reshade.me Also it works on Windows 10. Edit: I personally use Framework for Arma 3. I have an easy .ZIP package set up with installation instructions if you want here: http://sfx.thelazy.net/games/preset/2951/

I'm not sure if anyone has gotten SweetFX Configurator to work specifically for the game Arma 3 on Windows 10. It is possible that some users have done this successfully, but there is no guarantee. It might be helpful to search specialized forums or community websites for other users' experiences to find out if and how this is possible.
